I would greatly appreciate any insight on this topic from someone who deployed a system into a production environment. I run asterisk in my home and am used to my Asterisk box and Broadvoice account. Having said that, I know of asterisk connecting to a sip proxy and then being able to place/receive calls after the routing is established.
Im looking to deploy a small machine for my business, and am looking into DID numbers and trunks. Ive been reading the SIP URI FAQ’s on providers pages but am still a little curious how it all works in the background. I understand the whole routing of the phone numbers to the IP address of the machine, and how that will forward a phone call into the system, but I am not sure how the machine would place calls using the numbers. I couldnt find any information about a register and figure there is no proxy server on their end.
The network would look something like this…
-512kbps garunteed rate FR WAN connection
-all cisco equipment
-VLAN’s seperating voice and data
-QoS implemented inside the LAN (Im not worried about a QoS provider, i just dont want the data taking over any of the garunteed bandwidth)
-Asterisk sitting behind it
-6-10 local DID numbers
-15-20 simultaneous phone calls
-(Possibly Voxbone)
again any insight on this would be greatly appreciated. thank you.
